AIPAC! But Obama's got some time left, and you're right, he won't sway Netanyahu with threats, but he CAN certainly make things happen with action. One thing for sure though, if he wins a second term, which is actually very likely, he'll not be the deadbeat on ME peace that Bush was during HIS second term. And AIPAC's fangs will then be considerable shorter.
